you will need sugar, measuring cups, a quart-sized canner, a second large pot, a canning funnel, a jar lifter, clean quart jars, lids and rings:
(funnel and jar lifter)
Remove from stems:
Fill your canner about half full and turn on the heat so that the water can begin to warm up. Bring a large pot of water to a boil. Using the canning funnel to help you get the grapes easily into the jar, measure 1 1/2 cups prepared grapes into seven clean quart jars. (I run them through the dishwasher before I make the juice.) Add a scant 1/3 c. sugar. Carefully add boiling water to the jars leaving 1/2" at the top of the jars. Wipe off the jar rims with a clean cloth. Put on lids and screw on rings. Using your jar lifter, carefully put the jars into the canner. Add enough hot water to completely cover the jars.
Bring the canner water to a boil. Process (boil) the jars for 10 minutes at a rolling boil. Turn off the heat. Carefully remove the jars and allow to cool. Using a sharpie, mark the lids with the date.
